Guide to Amanitaceae
Members of this family have a universal veil. The base of the stem may have a volva or ridges or powdery remnants of the veil. The cap may have warts or one or several patches or powdery remnants of the veil or be smooth. But caps do not have scales. Some have a partial veil that often leaves a skirt-like ring on the stem. This family, based on DNA evidence, is closely related to the Pluteaceae and also the Pleurotaceae (oyster mushrooms).
